Maybe, maybe not. At the time Big West made MII, Kawamori was off the Macross ride. He did some occasional valks (like the infamous Stampede Valk) but at that point, Kawamori and co. were done with Macross. Big West may have wanted to do something for the 10th anniversary (i.e. MII), but that was done without input from Studio Nue. Without Studio Nue's input (primarily Kawamori), it wasn't really part of the Macross timeline.
The same could be said about Orguss 2. Big West created that show without input from Studio Nue. And it is not part of the Orguss timeline.
