At least in the '80s, the rule on synonyms seemed to be "is it in the dictionary"? (One that lists synonyms, perhaps.) The words in question really need to be combined before you can call them synonyms, and that goes beyond a simple look-up in a reference book.
You would actually have a stronger case for "critic(ally)" = "review(er)", I think--but still not one strong enough to get zapped.
