For all I know, that’s not possible, since comments depend on a Post ID to exist.
You can, however, mimic that functionality by registering a post_type to be at the same time, attached to one specific category, and parent their comments.
Then you can insert a secondary query on your comments.php to fetch the post_type entry associated with the current category and display its comments by that category’s posts.
