Logically, no. ENT is common to both universes, by definition, since Nero's incursion occurred decades after it took place.
Quite frankly, let canon be disgraced on this one, but Enterprise really had nothing to do with TOS. Even before the 2009 movie came out, when I was watching it on DVD I was finding it hard to believe that Starfleet ships of the 2150's could look so much like their counterparts of the 2360's, instead of the 2260's. So, in terms of design, and don't try to tell me that it's because TOS was based on 1960's assumptions, compared to TNG's 1980's/90's assumptions, I also felt like the producers of Enterprise were trying to shove TOS out the airlock, and say that between Enterprise and TNG, we don't know what happned.
But TOS *was* made in the 1960's, and set and ship design can be changed as easily as an actor is recast. They have nothing to do with the story. Kirk is William Shatner and Chris Pine. The Enterprise is the Enterprise whether it looks as it did in 1966 or 2009. A Romulan Bird of Prey is the same whether it looks as it did in "Minefield" or "Balance of Terror"

on the subject of visual continuity.
So design wise, the 2009 movie looks like it belongs in the same universe as Enterprise. Plus, storywise, it doesn't jar you with annoying continuity questions like 'If humans had already met the Ferengi, then why did they not recognize them from the history tapes in "The Last Outpost", even though they had no name attached to them?'
Unrecorded (for whatever vague reason) first contacts have happened in Trek before - Robert April and George Kirk learned the Romulans' secret in Diane Carey's Final Frontier
, the Borg's initial encounter was rewritten in Voyager and Enterprise (and at least one TOS comic)
And it's not like pre-Enterprise continuity was flawless. Trek is entertainment first and foremost. TNG wasn't too bothered to pretend the earlier comment about Romulans having not been seen or heard from in 50 years ("The Neutral Zone") never happened when they wrote about a huge Romulan incident 22 years ago ("Yesterday's Enterprise") and Voyager merrily slowed warp speeds down to suit it's core plotline, making TOS' galaxy-crossing journies (and thus the events of several episodes and one movie) impossible.
