no, forge just has their own implementation of modloader. so if you have forge mods, just install forge and it will load your modloader mods as well. obviously not guaranteed to work since they have to follow risu's updates in order for them to load properly, but this is the only way to have both. just don't install both loaders, that's the only wrong way to do it. yet we still have pages and pages of crash spam from people who refuse to read.
choose either forge modloader or risu modloader, this doesn't mean you can only use one type of mod. if you only run modloader mods then use risu's, if you want both forge and modloader mods then just use forge, it's not that complicated.
