What was not tested
Assuming you have Dropbox installed to $HOME/Dropbox, simply save your "local" budget under "Z:\home\\Dropbox\YNAB" or something like that. Works flawlessly.

The preferred way:
I have Dropbox for Linux installed. Instead of futzing with getting it to think I had Dropbox installed in "windows", I just told YNAB to store its Local Budgets in C:\users\MYUSER\My Documents\Dropbox\YNAB. My Documents is conveniently a sym-link to /home/MYUSER and my Dropbox folder is /home/MYUSER/Dropbox. Works like a charm. Tested with the iOS mobile app.
Sometime it happens that YNAB comes up only with a black screen. It seems that your graphics card doesn't support fully OpenGL - you will need to disable it like this:
env LIBGL_ALWAYS_SOFTWARE=1 WINEPREFIX="/home/USERNAME/.wine_YNAB4" wine C:\\Program\ Files\\YNAB\ 4\\YNAB\ 4.exe
