I think you're overanalyzing. Everyone always asks whether Harrison Ford was an android in Blade Runner. I'd find it hard to believe that Ridley Scott would make another movie posing the question of "is he/she an android?" I think the simplest explanation for the hyper sleep bit is that Charlize had more experience with cryosleep than the rest of the crew. Fassbender had to tell Rapace and the rest that their bodies were in shock. Vickers, on the other hand, was an executive who planned the mission. She might have done a few test runs and gotten mentally used to the effects. She was still sweaty and nauseous when she woke up. She started to doing pushups to "buck up."
