Yes.

You should be able to reference a dll on MTS from within VB6. If you can't find it in the list, you need to go to MTS and create a Package of the components you would like to use. This will create a small exe with a DLL stubs of the components you want to use. These stubs, and the exe must be copied to the client, and the exe must be executed. It registers the MTS components on the client.

Your client PC must obviously be able to see the Server that the Components are registered on. Hope this helps
