You can use PI AF with your FactoryTalk historian; there are no licensing or technical issues.
As far as the system requirements, those are documented in the PI AF Installation Guide.
I've inquired about your query with our Product Managers to see if there are any licensing issues.
I'll advise as soon as I hear from them.
Have you checked with Rockwell Support for this request? From looking at Rockwell's site, it looks like FTH SE 3.0 and 4.0 come with a Factory Talk Asset Framework Server product, which is required for installation.
