If you YouTube it then there is a video showing how to remove it and the steps you see are easy enough to remove the battery with the correct tools however since the battery uses connectors on it to place into the board then unless a battery has been developed with a new back to fit I doubt it would be of any use unless your battery is dead.
Long answer, when the battery is wearing out in a couple of years it will be possible to replace it, assuming you can get an OEM battery. It is not possible to swap out a charged battery for an old one on a daily basis.
