They don't interbreed with either common Norway rats nor mice.

I'm not very knowledgeable about ASFs. But like what Redneck_Crow said, they're a different species as Norways. They're of the species Praomys natalensis. I believe ASFs are more commonly known as Natal Rats to the pet community. But I could be wrong.
Oh, well I guess thats good to know, learn something new everyday
