You are allowed to make minor changes to your itinerary after you get the visa.
You are not allowed to misrepresent your itinerary to get your visa, and you should avoid giving the impression that you lied.
Since both the old and the new itinerary would have Germany as the main destination, it sounds unlikely that there would be the suspicion that you lied to get the visa.
