I doubt he is Khan.
One thing we seemed to have forgotten is...
The Prime Universe Original Series had a character named "John Harrison" who was NOT Khan. He was just John, a background character seen a couple times going about his routine duty.
A couple weeks back, (I believe it was) Alice Eve said [paraphrased] it was fun watching us freak out over who JH is when the answer was really very simple. Isn't the simplest answer that JH is simply JH... The same character from TOS but, due to changes in the timeline after Nero's incursion, living a different string of life experiences?
I am not saying Khan cannot somehow be involved, just that, given all the evidence we have the likelihood he is Khan Noonien Singh is slight at best.
Actually, there were two Harrison. The one that you've refer too; And William B. Harrison, flight officer of the S.S. Beagle.
