single pole switch controlling light, recepts hot, power in recept one

In this video the power runs through recept one, then the switch box, and finally to recept two. To keep the videos as short as possible I do not staple the wires to code and i may not cut in the light box.

In this setup is it possible to run a cable across to the empty box and add another light fixture and control it with the same switch

yes, you can run more lights of the switch
