That entirely depends on how you define it.
Mathematically, there is not any difference. A polygon is just a "surface" - i.e. coordinates are stored for each point. So an asteroid in Asteroids is a polygon - though they are 2D (and so obviously just two coordinates per point). Maybe something like Star Wars being 3D geometry (at least visually) - so the sides of the H fighters are all polygons. I wouldn't like to think how they could calculate that in 2D - but one game certainly did it - Battle Zone - that was fake 3D, but then you only moved in 2 dimensions anyway.
You could say that you wanted to know the first game to use hardware driven polygons (maybe Asteroids/Star Wars do though) or perhaps they have to be solid polygons to qualify.
In this case, the first game I know of to do this is I-Robot.
