On the Pro plan, yes!
The Extended license covers client work.
The Standard license is for personal projects.
When you license a track within your plan, this provides clearance for the use of the piece of music in a specific production, irrespective of who may be using, publishing or distributing the content. This means that whether the content is distributed/published by yourself, your own company, a client or another third party, the music is cleared to be used in the production, so long as the content and distribution is within the scope of your chosen plan.
