Yes, just draw some cat6 between the locations and either connect to it directly/through a switch or hang an access point off the work room end. In the latter case you configure the access point to the same SSID and password/certificate as the one in the living room while using a different set of channels so your equipment will not need to be reconfigured (you may have to manually toggle wifi to get it to connect to the nearest AP since hand-off is not part of the standard). In nearly all cases you'll be able to find some path for the cat6 which makes it close to invisible - ventilation ducts, along central heating pipes, through old conduits meant for copper phone lines, along base boards, etc. Do not use power line conduits for this purpose, that is against a number of regulations and also can cause interference and stray current flows through induction. Why cat6? Because it is hardly more expensive than cat5 and more future proof. If you don't care about the latter and have some cat5 lying around, by all means use it but if you have to buy the stuff anyway you may as well choose the 'better' option.
