Yes, you can pull it up, but the problem is that when you pull it up, you'll need to take the plastic cover off again and push the pin manually to push them back down.
I am going to order a couple of plastic covers with buttons so that I don't have to hack this again. Just press both buttons and you can even take the headrest out! Or, I can just cannibalize a plastic cover from one of the rear headrests. I am sure it is the same part number. From RealOEM.com, it seems like I can't just order a plastic cover w/button separately. It comes with the entire locking mechanism assembly.
