I've searched about this, and long mode supports 16-bit protected mode, but not real mode.

There are also some hints that this goes for pure application code only, and that operating system (and I assume extenders) level code might not work (e.g. the unavailability of certain TSS features in long mode).

Since afaik win16 apps are pmode, they may indeed run technically, but win64 doesn't support it.

Afaik Linux never had support for 16-bit pmode.
