Yes, that basiclly is possible. What you are speaking about, technically is a move to your other, local PC. See Manual:Moving_a_wiki for more information on server moves! Then what you do is an upgrade as detailed on Upgrade and then another move back to the original server.

I have not tested a Windows <-> Unix move myself, but I would expect the following:
 * Configured file system paths have to be adjusted (e.g. in LocalSettings.php, but possibly also at other places).
 * All caches have to be cleared.
 * If the domain name/URL of the server is different both times, that will have to be adjusted as well (e.g. in $wgServer).
 * Additionally, the objectcache DB table has to be cleared - otherwise there will be a flood of "file not found" errors.
 * It might be possible that you have to adjust some paths somewhere deep inside the DB; I do not know if and where, but that it would be e.g. is the reason for why you have to TRUNCATE the objectcache table.

Usually it won't be reasonable to go down all that way moving a wiki just to do an upgrade. The few bucks you save for not paying a more expensive hosting will easily be spent for the working time needed to do the server moves.
