Not necessarily. Laptop might not be refurbished by original manufacturer, or an old (defective-style) battery might slip past quality control. These batteries tended to spontaneously combust.
There have been various instantiations of the 'exploding laptop' over the years. But in all cases there has been a recall of the defective hardware and it has been replaced. I fully admit that you could have a laptop with an older faulty batter or such, but it is a very unlikely scenario... that's something the manufacturers take quite seriously.
But for new hardware, how do you know whether it is a defective product line with some variant of the 'exploding laptop' issue? You won't until the first batch of accidents happen. But buy from an older established line and you can be pretty sure about whether you have to worry about any intrinsic defects.

On a "refurbished" computer, expect it to be cleaned, erased, and have broken parts replaced. This is not always done (i.e., old, and possibly infectious, files remain on hard drive -- as has occured with many computers obtained from Best Buy).
I have trouble imagining Best Buy wouldn't do a clean wipe. I mean, if you send your computer back to them for
any reason, it gets a clean wipe. (very annoying)
It would be pretty unorthodox for them to just delete files without wiping (and probably worthy of a class action suit against them), although I wouldn't be surprised if someone had simply trojaned one of their OEM discs. (in regard to your anecdote about infected files)
Harddrives are the one thing you don't want second hand anyway--they're the only (significant) bit of the computer with moving parts. Also, the only way to be absolutely sure that no one can recover your data off them involves some variant of smashing them with a hammer, so you shouldn't ever let Company X have your drive when you retire an old computer (hopefully, Company X will not be reusing old drives anyway).
Regardless, I think we will both agree that the first and most important rule of buying a computer is to not get it from Best Buy.

Keyboard, monitor, fingermouse, and powersource/fan will not be replaced if they are deemed operable. All of these components are subject to wear, and have limited lifespans.
"Limited lifespans" yes, but if you don't do anything stupid with them they are for all intents and purposes immortal. You might lose some pixels in your LED display, and the power converter might die if you use it incorrectly, have a surge, etc., but there is no good reason for any of those things to die from normal use if they aren't shipped defective. For that matter, apart from the panel, they are all easy to replace... in fact, my first order of business with fingermice is to disable them.
But that's all entirely moot because you should not be buying a refurbished computer without a proper warranty to go along with it. The consequence of your screen dying should be simply that Dell comes out and gives you a brand new one.

You cannot replace laptop components yourself, as with a PC. PCs are safer to buy refurbished, or even used, as one can work on it themselves. Laptops require special tools and training, and the miniaturized components are more prone to failure.
You can indeed replace laptop components yourself, and while it is not
quite as a convenient as replacing components in a newer PC (it comes close), it is a lot easier than replacing components in one of the older systems.
In fact, if you've ever had to go through Dell support for a bricked lappie, they always have you go through and remove all of the components to see if any of them is the culprit. If they expect Joe Customer to be able to handle it, it's not that tough. The only major difference between that and working on a modern desktop (as far as replacing wireless card, harddrive, ram, cd tray, etc.) is that laptops still require removing some screws.
