The PA has been running 7 car trains on that line since it re-opened after 9/11. There shouldn't be any reason why they couldn't run 8 car trains right now.
A later article at http://www.nj.com/news/jjournal/index.s ... xml&coll=3
says that the Exchange Place station needs to be modified to support longer trains. It was already extended as part of the post-9/11 reconstruction. I haven't measured it to see if it can handle a full 10 cars now, but I'd be very surprised if it can't, as the PA has long wanted to lengthen platforms on this line and the reconstruction gave them that opportunity.
As Newark, Journal Square, Exchange Place (probably), and the WTC stations can handle longer trains now, the PA could use the old "first car does not open at Exchange Place" method to cut out 2 cars at Harrison and Grove and run 10 cars - if they had enough spare cars in the fleet to do so.
But, as I mentioned above, they used to run 8 cars and could do so again.
