In my experience, no. They only just recently added support for executing apps between environments.

Executing Windows apps from the bash shell can be surprising:

$ notepad The program 'notepad' is currently not installed. You can install it by typing: sudo apt install wine1.6

$ notepad.exe (Note Pad is launched)

$ /mnt/c/Windows/System32/notepad.exe (Note Pad is launched)

In the latest builds symlinks no longer require administrator permissions.

Don't know what you're referring to in regards to permissions mappings, but know that the Windows' permissions always trump whatever your see from chmod/ls -al
