Yes and no. I think you could call W2 1095 but not the other way around. 1095 is a wide spec material. It is possible, within the specification for 1095, to have an alloy who's pearlite nose goes all the way over and touches the left side of the graph. This would not be very useful for knifemakers. 1095 is an inexpensive wide specification high carbon steel.
W2 on the other hand is a relatively clean (think: vacuum remelt) narrow specification tool steel with vanadium for grain refinement. Clean low alloy fine grained steel sports some of the best fine edge stability that steel is capable of. A W2 standard in my cut tests has the most durable fine edge stability of any steel I've tested and I've tested quite a few. Not so with 1095.
