At a first glimpse I would say: Yes.
But thinking further and checking official sources the answer must be no.
The building has just one adress (GVB-Nummer) 42c, so dividing it would leave one part without adress or two parts with the same adress - which both would be wrong.
The only "good" way in my eyes (as I see it for the moment) is to set an amenity place of worship as a point in the eastern part of the building, the western part is where the appartment is.
If this sounds good for you as well I might do it during the next days - I live nearby, so it is kind of "my" area.
