It depends on wich type of sponge I imagine, but I have cut a few of mine either intentionally or by accident and glued them on liverock without any ill effect.
It is only dangerous when some sponge die if they turn white. I have a blue photosynthetic sponge that is incrusting and I am cutting piece of it to cover an artificial sponge so eventually it will cover the whole artificial sponge with a beautiful blue natural sponge (so I hope) and each time I can I cut pieces of if and glue it and they always have stay alive and spread nicely.
You could probably cut it at the base and remove it if you wish, or just let it set on some liverock. If you see that it is turning white, then remove it immidiatly and throw it in the garbage as a sponge that is turning white usualy mean it's dying.
