Not necessarily. You could make the screen object single sided (as is the LW default) to ensure that the light can shine through from behind it.
Gobo is a lighting term - also known as a 'cookie cutter'. It refers to a mask placed in front of a lamp to 'shape' the light that comes through it. By making a gobo with a cutout the shape and size of your screen you can mask off the light that would spill out to the other side.
The best bet you would have for a reasonable result I'd say would be to parent a large box to the Nintendo screen, and make it 100% dissolved for the animation, then pop a volumetric spotlight in there and dissolve out all the parts of the scene that won't be affected by it to help speed up the render. Then render it in a separate pass and composite in post...
