I was going to move this to the general Parrot care section where I believe you would have gotten a better viewing, but I didn't work, so I will give my answer here.
Macaws have a problem in being housed in the same room with what are called " dust birds". An African Grey is a dust bird because like members of the cockatoo family they produce feathers that turn into a special dust that waterproofs the birds feathers. This dust can cause respiratory distress in Macaws. So my answer is that you should not house them in the same room.
