I've only tried this once, but they denied it, because I was using IKK (though the final ticketed itinerary had no AC after LH F opened).
No, they can build two identical trips on two screens to get everything on hold, but if payment will be from two accounts it must have two separate PNRs. They can link the two PNR, which in my experience usually gets seating assigned together on other star alliance carriers.
