Yes, you can remove any differential backup up to the most recent one. The differential backup will include anything that has changed since the most recent FULL backup. However, keep in mind that a backup is only as good as the last time you've restored it. In other words, if you delete all the previous backups and the most recent one is corrupt, then you might be hosed. Just something to think about. Hope this helps!
