Translating syscalls and translating opcodes (especially efficiently) are different things.
And we don’t.
But yes, this is possible and Windows for ARM includes such a translation layer. Except it’s not very good yet.
In some sense ARM everywhere is a nightmare. There’s no standard like EFI or OpenFirmware for ARM PCs.
I hope that changes.
