In other words, you could (unofficially) do this before, but now it's allowed according to the terms of your license.

It looks like Parallels has the same restrictions that you'd get from running Win11 ARM inside the UTM hypervisor on M1/M2 Macs (like I currently do): No WSL/WSA and no virtualization based security or sandboxes.
Why would you need WSL/WSA when Mac is already a *NIX?
Yes, macOS is a BSD - UNIX Certification and POSIX compliance is nice, but macOS does not behave the same way as Linux, which famously is not a Unix (it's even in the name), and POSIX compliance doesn't mean much today: even Windows 2000 and Windows Server 2003 were POSIX compliant with SFU.
From what I gather from people with far more experience than me: if you need a "Linux-compliant" environment you're better-off with WSL2 than macOS.
I'd argue you're better off with macOS + something like Parallels or, if you just need ubuntu, multipass. Introducing Windows to get a Linux-compliant environment is reaching around your back to scratch your elbow.
