There was a trip report that apparently someone was let through immigration to go to T4S so it may be worth a shot (understanding that if it doesn't work you'll have to take the train back and re-clear security). I would imagine it's probably more likely to work if you have an EU passport. Remember to get back to T4 main you will have to re-clear security regardless so you need to plan a healthy amount of time to get back.
