SQL Server 2016 Licence Hope you can help me out. 

My current SQL setup is as following 
Two SQL Instances (2012 and 2016) stacked on a single virtual machine. With the SQL components SSRS and SSIS 2016 installed on same.

The only reason I did this was two lower licencing costs. My 2012 instance is primarily for older apps that aren't certified on SQL Server 2016. With the goal of moving all my databases over to SQL 2016.

My problem, I've had a request from a supplier for a  standalone virtual machine with SSRS 2016 installed for there reports only. I don't believe we are covered to install SQL components such as SSRS and SSIS on a separate virtual machine. 

Any thoughts ?
Thanks
