AFAIK, there is no difference between Windows Bitcoin Core and a linux version of it, it is possible to compile it yourself. You can download a linux version of Bitcoin Core without compiling here: http://bitzuma.com/posts/getting-started-with-bitcoin-core-on-ubuntu/. If you really need to compile, here is the compiling guide: http://bitzuma.com/posts/compile-bitcoin-core-from-source-on-ubuntu/. If you really need to run a Windows version, use VMware.
