Yes.

FAIR TERRITORY is that part of the playing field within, and including the first
base and third base lines, from home base to the bottom of the playing field fence and perpendicularly upwards. All foul lines are in fair territory.

So strictly speaking the face of the fence is the boundary. If the ball hits the top it has gone over the boundary.

The official MLB ruling is that if it hits the top and goes over it's a HR, if it hits the top and comes back it's in play, and if it hits the top and stays there it's a two base award.

If it hits a yellow line it's in play.
