It could as long as critical AoA isn't exceeded. Additional pitch at risk or cost of a tail strike might well allow the plane to fly. Sounds like that was the case in SEA.

Aborting above V1 is not typical, but there are a few situations where it might be necessary. This would probably be a lot more rare though, because how did you get to V1 if your acceleration was too low to get you to V2? If acceleration to V1 was off, it would probably already have aborted.
That assumes that it knew the correct values for V1 / Vr / V2. It would not have in our SEA example because the numbers generated by a separate ground-based system were garbage. You know what they say about garbage in....
In that case the right answer was to scrape the crap out of the tail if necessary to get airborne.
