I've only read a little bit about this so could well be wrong, but it seems more like WINE in reverse, except the translation layer is part of the Windows kernel, "Windows Subsystem for Linux", instead of being a separate userspace program like wine(1). Thus it takes ELF-format executables that make syscalls to the Linux kernel, but a new bit of the Windows kernel is happy to execute those, compatibility, instead. The restrictions include: the Linux program's view of the filesystem being what fits Linux's model; there's no view of the registry; Windows' processes aren't visible; you can't run a Windows executable like notepad.exe. It's a bit of a silo, which I guess is your chroot reference. These things may improve, they say. https://blogs.windows.com/buildingapps/2016/03/30/run-bash-on-ubuntu-on-windows/ has MS answering in the comments.
