Nothing really "contradicts" Cell's statement, though. He said that he possessed enough power to destroy the solar system, and the guidebook corroborates his statement. Obviously we never got to see Cell physically destroy the solar system, because Gohan killed him before he could do so. This does not "contradict" his statement in any way/shape/form, however.
Now, had Cell tried, and failed, to destroy...say...the sun, a legit "contradiction" would exist. But as it stands: we have an in-universe statement, backed by a canon guidebook, stating that Cell was a solar system-buster. Typically, that is enough to canonize the statement(s) in question, so long as no blatant contradictions exist(and none do.)
That being said, whether or not Cell could destroy the solar system means very little to me--I could care less one way or the other. I'm just saying that his 'baseless claim' is also backed by an outside/canon source, which we must take into consideration. Furthermore, Cell might have only been able to destroy the solar system through some sort of chain reaction for all we know(ie. he destroys the sun's core, and the resulting detonation creates a domino effect which "blows away" the rest of the solar system--not unlike Freeza did to Namek, but on a much larger scale.) Who knows..?
