Definitely, like anything that rotates around a central axis, the centre moves much slower than the extremities. A good example is taking a shot of the sky on a fixed tripod. At a given exposure, stars near the SCP will always exhibit less trailing than those further away. For example, with a 50mm lens you might get away with a 20 sec exposure at f2, 1600 ISO around the Crux constellation but try the same exposure near Orion and there may be star trailing evident.
