Does my regular license allow me to use the theme also on subdomain ?

The company I bought this theme for provides local and global tours. So i need to separate tours somehow to make it easy to access to the content and not get lost between two types of tours. So we need local tours on separate subdomain local.tours.com and global tours on tours.com.
My question is do I have to buy this theme again even if it is the same company website same main domain ?
