Of course you can't. That's why you don't just take advertising at its word. Anyone who does is a fool. But to say that you shouldn't allow comparative advertising because of the possibility of lying is absurd. There are other laws that cover truth in advertising.

Using someone else's brand, without their permission, in a way that will damage their brand, to try to sell your own goods, in a way that everyone knows is going to be fantastically biased. Seems pretty out of order to me. :)
