AFAIR yes (seen this been done for the logo). There is just the one instance
of KAboutData as created in the beginning, no data is copied, so operating on
that instance will get you what you want, as KAboutDialog is using the content
of that instance (on first show only? no idea if the dialog is cached, but you
should be able to do the modification before the first show).
