Most probably, yes. The "C" drive is held in your WINEPREFIX(default is 
$HOME/.wine), and will not be deleted as with any other application out there. 
Some package managers have the ability to detect the setting files/folders in 
your home and delete them, but I don't know any package manager to do that 
without asking to.
If you always use your package manager to install wine, you'll most probably 
don't need to remove the old version manually. Your package manager will do 
everything for you(true for dpkg, rpm, pacman, ...).
