As well as my CV 35/1.4 I also have a Summicron-C 40/2. The 40 is not really a substitute for a 35 in my view - it has a noticeably tighter angle of view.
The "40mm with 35mm frame" thing is really just that a lot of people find it easier to frame a bit tighter than a 35mm frame than a bit wider than a 50mm frame. It's certainly what I find, and my 40mm is filed to show the 35mm frames on my Leica Ms.
The accuracy of framelines in different cameras varies - some are tighter, some more generous, and I have no idea of the frames on the ZM. To find out how close the 35mm frame is to a 40mm view you really need to do some testing - do some shots with obvious markers at the edges of the frames and see what actually appears in the shot. Once you've done that, you'll be able to make a decision on whether the 40mm lens with the 35mm frame suit your shooting.
The 40 S-C is a wonderful lens though - I got a Bessa R3A specifically for use with it.
