Wine on Windows 10

Virtual 8086 mode isn't available when running a 64-bit OS, so the virtual DOS machine code simply won't work there. This is less of a problem with most 16-bit Windows applications since the limited 16-bit functionality they need is still possible under a 64-bit OS but making this work requires some extremely hairy kernel code.

You could just run it in an emulator. And microsoft has written a virtual 8086 emulator for virtual PC. Virtual 8086 mode was just a virtual machine anyway.

NTVDM used to contain an x86 emulator included for running DOS programs under Windows NT on non-x86 platforms (Alpha, MIPS, PowerPC). There is no reason in principle why they couldn't have used that existing code on x86-64. But, I assume they decided that the cost of doing that (in developer time/etc) wasn't worth the benefit. (Running DOS programs has little commercial relevance any more, and the small minority who still have a need for that are better served by more fully-fledged virtualisation solutions such as Hyper-V, VMware or VirtualBox.)
