It all depends on the qualifications of people playing in this tournament.
It would be possible to fold if you were already in ICM or were very close to it. But you said that there are 16 more people ahead of you. How do you plan to overtake them, if you want to off hands such as AKs, I think this is a call. On the other hand, if the players playing in the tournament have a hard time understanding ICM, and they make mistakes, you can wait.
