Yes, but I suspect that is a function of geometry. For example, it is possible to have a lighthouse whose beacon is spinning so quickly that the spot of light in the distance (at some distance "r") is moving faster than c, even though the rotation of the lamp is not faster than c, nor is the actual light beam.

In this case, probably a function of 4-D geometry (which we can't visualize, being only 3-D creatures). But we can describe it mathematically.
