I am sorry for you, you have a boss who judges book by its cover. Well you can always call him after the program is started and show him how it works :) that may change his mind if he is really wanting to change it that is.

Of course, other people complain their boss cannot handle the name "gimp" because it's unprofessional.

In any case, I've given you a solution. And, of course, it's not something you have to do on all the devices, you download Krita's portable zip file version, if using Windows, adapt the .lnk file one, and then roll out the update by creating a new Windows image with the modified version of Krita.

At least, that's how professional organization handle OS and application provisioning.
