Yes, but only for as long as Google allows them to do it in their Chrome mod. Microsoft will keep away from centain Chrome features in Chromium as long as all they need to do is to turn them off. i.e. stay on the same trunk but without certain optional element. Key here is - optional elements. If Google will change something that will require to branch Chromium (and I mean really branch, with internal changes) to stay away from such changes, I highly doubt that MS will do it. They don't wan't or can't to maintain a separate different browser as they already shown with Edge.
