I think all points on the circle can still be equidistant from a center point, regardless whether the distance is calculated as a trace along the actual surface the circle is on or straight line directly between the points on the circle and center. So it should still qualify as a circle. But it seems easy to vary the contour of the surface in a ways to almost arbitrarily increase the circumference of this circle.
