Something that should come up early in sentence diagramming but often isn't explained well enough is that sentence diagrams aren't context free, often can be ambiguous, and depend on the context of the speaker to determine referents. Sentence diagrams in the real world are rarely as easy as elementary school examples. In this case, the context known to the speaker but often missed when trying to "sentence diagram" WSL involves the part "Windows Subsystem". That referent, to which the original author was quite familiar, is invoked in WSL as a single noun in part of the larger noun phrase, and while you could continue to sentence diagram break "Windows Subsystem" into constituent parts here, it is important to remember it as a single connected "atom" to which "for Linux" modifies in the overall noun phrase of "(Windows Subsystem) for Linux". Given that context/referent, the sentence diagram here is unambiguous to the original team/"speaker". It's the audience with much less familiarity with the referent/context in question that has ambiguity problems in trying to "sentence diagram" the noun phrase.
