I know two opinions:
"Central" means "very important" (as it was central problem in probability for many decades), and CLT is a statement about Gaussian limit distribution. If the limit distribution of fluctuations is not GaussiaGaussian, we should not call such statement CLT.
"Central" comes from "fluctuations around centre (=average)", and any theorem about limit distribution of such fluctuations is called CLT.
Which is correct?
