Find out if a view returns any results and if it doesn't disable a link to that view
The one solution is hide empty terms. You can hide empty terms as shown here

Another solution is use php in your view or views template, use taxonomy_select_nodes function.


  Return nodes attached to a term across all field instances.


The tid can get from view. If the function return empty , dont provide link for that term.

Otherwise you can link term to your second view.
