Great question — answering as the UphillTech team:
I don't know much about Nyarlathotep but if he is physical to the world then no. Bill had to possess someone in order to have a physical form. Otherwise he only existed in the brain. So probably not. But Nyarlathotep does look like someone/thing that would exist in the nightmare realm along with keyhole, 8-ball, and kryptos.
