It's not impossible but you can't limit your definition of bunt. A very hard push bunt could possibly hit a gap and roll a long way. A girl with speed could score. A hard slug bunt could also do the same thing. Now your basic bunt, that's another story.

Yes you can limit your definition of a bunt.
