There is two parts to this:

1. The ‘moderator’ role cannot be currently set to only disable moving topics to another forum currently, to change this though a couple of tweaks to the form-topic.php template would achieve this end result.

2. There is also a bug where moderators can move a topic to a group forum that they are not a member of that we are looking into in #2639
