The last movie made mention of Admiral Archer
Yes, and Memory Alpha pointed out that Archer would've been 145 at the time of Abrams-Trek, which I personally think it more than pushing it.
If you remember the dialog, the movie actually mentions Admiral Archer's beagle
Archer himself could have been dead a half century by that point.
My private theory is that Porthos is also dead by that time, but his body is preserved and on display at Starfleet Academy, Porthos is Starfleet's mascot. Scotty stole it from the student union for his transporter experiment.
