You don't run your ASP.NET MVC on Linux boxes, though. On non-IIS web servers, and likely you use SQL Server and the LINQ libraries....unless you'r using Mono (which has a lot of hurt involved to do so, especially once you start getting in with external libraries that your application might depend on).
in general, when people mention ".NET STACK", they're talking about the whole-shebang, not a single library that might happen to be OSS when the other 100 libraries you're dependent on aren't.
