No, that would be dishonest: they are no longer Debian logos. You
should give names to your edited files that indicate what they are:
/your/ images for /your/ derivative. Add them to the archive and
change the symlinks there. You should end up with something like:
drwxr-xr-x 2 root root 0 Mar 22 2022 usr/share/graphics
-rw-r--r-- 1 root root 14649 Feb 15 2021 usr/share/graphics/logo_debian.png
-rw-r--r-- 1 root root 14649 Feb 15 2021 usr/share/graphics/logo_debian_dark.png
-rw-r--r-- 1 root root 12345 Oct 15 23:59 usr/share/graphics/logo_marietto.png
-rw-r--r-- 1 root root 12345 Oct 15 23:59 usr/share/graphics/logo_marietto_dark.png
lrwxrwxrwx 1 root root 15 Feb 15 2021 usr/share/graphics/logo_installer.png -> logo_marietto.png
lrwxrwxrwx 1 root root 20 Feb 15 2021 usr/share/graphics/logo_installer_dark.png -> logo_marietto_dark.png
