Paid Charge Off worth trying to remove

I'm working on cleaning up my husband's credit and he has several things one of which is a paid charge off. The DATE OPENED: April 17, 2010, but it shows LAST UPDATED: Sep 30, 2016.  I am currently sending a dispute letter to remove 3 authorized user accounts from his CR and I am wondering if I should or even could try and get this paid charge off removed? It's pretty old, but I am wondering if dispute it, would it automatically get verified because it was a paid charge off or reset any fall off dates because I inquire about it?  Should I just let it sit until April 2017?

Thanks
