Emulation is possible, and now even easy. Windows has a built-in Windows on ARM (WoA) feature, and Linux can do something similar with QEMU application-based emulation (including stubbing out calls to dynamically linked libraries with calls to native ones).

This is in addition to the fact that a lot of server-based code runs as an interpreted/JIT language, or a bytecode VM like Java or .NET.
