If you mean the Kodi TVaddon aKpplications, then yes.
Kodi has nothing to do with the services m3u Playlists.
The Playlist you are talking about would come from your service (Rocket or other).
Kodi and its applications are a different thing and you can stream as many as them as you want and at same time as your service, it will not matter.... but do not use your service (with that m3u playlist) on more then one device at sam time, thats a no no.
