It is not a traditional emulator which is a virtual machine that executes foreign bytecode or ar least uses a virtual hardware setup. QEMU fits that sense of emulator. Wine doesn't. Wine lets userspace code to be executed as is with the full permissions of the host system. It is more like an alternative executable format support package / subsystem. It needs to emulate the Windows system DLL calls, but everything else is no different than loading a piece of ELF executable and jumping into it.
