I've often thought of orcs occupying a similar role as horse nomads in real-life history - the equivalents of Mongols, Comanche, Huns, and the like. Roaming bands of "barbarians" that terrorize surrounding "civilized" communities. So they could live in the central Asian steppe and the North American great plains. The Sahel and savanna areas of Africa might also support such a culture, or the Pampas of South America.
