Volker,
Could very well be. When you get to similar looking corals it's a tough call. Even the experts have to go to skeletal comparisons and even that is not always 100% sure.
I'm not an expert in coral id but I have Jacquelineae and it's much thinner branced and blunter on the tips. Mine matches the coral skeleton on the AIMS sight better than the live coral images for the same coral though.
I also have a coral that looks very much like yours there and it was sold as A. caroliniana.
But who knows.
