Actually, the magnification - DoF relationship holds true at any distance. If the magnification, in your example the frame size, is the same then the DoF will also be the same at the same aperture (F-stop & not the actual pupil size). Of course, an F2 lens will have one stop advantage over an F2.8 lens as a shallower DoF can be achieved at F2.
