Sure, NT4 ran on X86, Alpha, MIPS and possibly other architectures (PPC?). I don't think portability for the OS itself is an issue. However, demand for backward compatibility mixed with lack of portability in legacy code led to the domination of the x86 architecture.
Anyway, recent processor architectures have so little to do with the original 8086... The x86 instructions are internally translated to micro-ops. Therefore, the ISA doesn't seem to stifle innovation.
