Assuming this is Xboard you are referring to...

Not as far as I know, I don't believe Xboard/Winboard "knows" enough
state about the current state of the chess game to establish if a move
is legal (I believe it misses certain castling restrictions, and certain
draws). It does a pretty good job, but I don't think it aims to be
complete, as it doesn't need to be.

If you input an illegal move to a compatible engine it will reject it,
and I believe Xboard handles this nicely.

Using GNU Chess be sure to have a version after 5.04 for the correct
errors on illegal moves.
