No.

Yes:

  $ git rev-parse HEAD~$N >> .git/info/grafts
  $ git filter-branch HEAD

This assumes that your history is strictly linear and you do not have
tags. It also rewrites the $N commits so that they now have different
SHA1s. For this reason, don't share this repository with anyone - it leads
to confusion.
