You could hide the name on every element on the board (I think the
keyboard short-cut is "h"), or: apply something like the following
patch. It may not apply cleanly, as it is from a personal stack of
commits on the top of my OpenGL branches.

I have needed this before myself, as typically - on boards where I'm not
going to have a silk-screen produced, I won't go to the effort of moving
every silk annotation into the correct place.
