I have heard it's dangerous to rockwell test an untempered blade. Is this true?

It's not a good idea to do anything to an untempered blade.
Except temper it, that is.

When doing an experimental ,or test, blade, all sorts of tests may done. Many are called destructive tests, such as bending and breaking a blade.Most all of these tests are not the recommended real world use of the blades. Testing for as quenched hardness is done to find the level of transformation and to help calculate the tempering temp.The blade can crack or break under the penetrator load. The test is done on the tang,BTW.
With a good blade (one you want to keep) , a piece of the same steel can be heat treated along with the blade. This gives a test sample to use.
