No, if there was no fee then I think Xbox Live would be of a much lower quality and therefore lose one of its biggest advantages over the PS3.
Now if Xbox Live was the same quality, but no fee (highly unrealistic) then sure, Xbox 360 could possibly have a lot more sales right now. Microsoft would be missing out on millions of dollars though, which would be money they could use to buy exclusive content for games, or purchase game studios.
