This is done by design for Fedora, just like the reverse is true for Mandrake.
If you're talking about modifying this behavior system-wide, there is not an easy way to do this without necessarily "breaking" the installed packages. You can try hacking around in /etc/xdg - but I'd really recommend backing everything up first so you can restore it when you break it.
For a single user, if you're in KDE, you can "delete" (actually disable) the menu entries you don't want through the menu editor. Don't know about Gnome...
