I assume that you say the cheat will automatically active without using the activator.(You should know JASS to do that)
But if not then how you active cheat with the activator is empty?
If that is JJ's CP. It will require the use of "-".
So no.
There are ways to make an empty chat command. I think it was CTRL+BACKSPACE making an empty message. Can't remember tough.

I think he's found a cheatpack inside a map, and wants to know how to activate the cheatpack without changing the map itself...and the answer is no, beyond extraneous activations, such as through name activators, (which is probably what your map uses).
