I would expect that to work, removing one should leave the other working.
However, if there is some general shared stuff that might break by doing this,
you could try removing both and then reinstalling just the one you want from a
starting place of none, and if the installation process touches shared config it
should set it in a way that works with the version you keep.

remove 15.8 and still have 14.5 work?
(15.8 was installed in error. I need to remove it in order to update WS_FTP
Server.)
