I cannot answer from experience for this combination of TV & adapter. But the answer is probably NO. This is because the operating system of such TVs usually only includes drivers for the internal WLAN module or for any external modules offered by the manufacturer as accessories. Most sticks from third-party manufacturers will therefore not work as a rule. What might work, however, are devices that function as WLAN clients themselves but are not connected to the TV via USB but via Ethernet. For example, there used to be the useful little Netgear WNCE2001which could even be powered via USB and "hidden" behind the TV without any problems. Unfortunately, it has not been available for some time. I don't know if there is currently a similarly space-saving alternative at Digitec. (Larger "boxes", i.e. mostly APs that are operated in client mode, are of course available in large numbers... but they may not be so inconspicuously "concealable" and so easy to supply with power).
