It's a pretty broad mechanism, also widely used in drama/anime/manga where you can basically stick any reading to any word as long as people accept it.

Traditional examples would be 本気 (honki) -> マジ (maji), 頭文字(kasiramoji) -> イニシアる(initial), 因果(inga) -> カルマ(karma)

I remember a live stream where a comment with "超電磁砲"(choudenjihou) was straight read into "railgun", as at this point the novel/manga/anime just established it as a popular reading.
