The CL lens' cam is shorter in "stroke" and very steep. The CL camera, which does not have to focus f1.0 lenses, has a simpler, shorter based rangefinder mechanism. The M cameras' rangefinder is fine tuned by adjusting the length of the roller arm which means that it can be in a slightly different position horizontally from one camera to another. The M camera's rangefinder may not couple to a CL lens correctly. Point the combination at a point at least two miles away and, if everything lines up OK at infinity, it should be fine. If it does couple correctly, bear in mind that it may not with another M body.
