Why not? You use libextfs or how is it called to read the file from the disk directly (read-only access), then you write it back using regular calls.
Of course, you can end up with "deleted" data being corrupted if kernel reused the area before undelete, or while you were doing undelete... but that's expected. They were _deleted_, right?
