It could. Much of my house is wired that way. Romex from the breaker
panel is wired to a node near the ceiling light. Cables from the
switch and all the receptacles in that room connect to that. You see 2
junctions with a lot of wires in them. One is a bunch of white wires
(including a wire to the light). The other is a bunch of black with
one white. That white wire is the one going to the light switch.
The "hot" node is not connected directly to the light. Doing so would
bypass the switch and keep the light on all the time.
