No it's not. If you don't believe me, unplug your PC's power cord and watch the light go out.
If the power cord is plugged in but the computer is shutdown, and the light is still on, then that means the network adapter supports WoL or OOB management and must stay on for that reason, but the network switch connected to the adapter is not physically powering any lights.
