No, DNF treats unmarked packages as installed by user => it never autoremoves them. Unfortunately, it seems that Packagekit is incorrectly marking all installed packages as dependency in dnfdb (#1259865).Note that packages installed by PackageKit are not marked as installed, so dnf always thinks it can remove them.
