A 747 of any type cannot fly level on a single engine (unless, maybe, there are no passenger, cargo and almost no fuel present).

A lot of flying today is done with two engines only, even over the Pacific or the Arctic. There are strict requirements. Google for EROPS or ETOPS. Modern engines are very reliable that diversion landings for other reasons (e.g. medical) are more frequent than engine failures.
E.g. the most recent version of the B777 will be certified to fly on one single engine for 330 minutes (ETOPS-330) in case of an engine failure. This gives enough room to cross even remote areas.
