From what I've read of it, the mechanism basically involves having the Windows kernel expose an implementation of the Linux syscall interfaces... so to userspace, it's just Linux binaries talking to what they think is a Linux kernel. That said, I don't know whether the emulation goes far enough to do an LFS build... e.g. does it provide support for /sys or /proc or kernel interfaces other than syscalls? It's designed to make life easier for developers porting server apps between Windows and Linux, but such apps don't generally need those interfaces - they just need glibc to work - so the emulation may not be sufficient for everything. /proc, /sys, and /dev are implemented. It actually boots Upstart when executing the subsystem. I at least remember that much
