It does not eliminate positional considerations or tactical possibilities. Given that chess engines are generally considered weakest in the opening, FR chess could certainly be used to test engine knowledge. But the problem is that it is difficult to say with any certainty what the best move is in a particular opening, since there IS no opening theory. Additionally, I suspect that, all else being equal, White has more of an advantage in FR chess than in regular chess, as Black does not have access to opening theory which allows for more chances for equalization and/or complications. This is just a thought, though.... jm
