 I see no reason why the English name for a group of German dialects should not be a translation of its German name. 

 Talking about "Central/Middle German language" seems as inappropiate to me as talking about, for instance "Australian English language". Varieties of English are called XXX English. Why should this be any different with varieties of German. Of course, the different varieties of English are usually more intelligible with each other than the different varieties of German, but that's a characteristic of the German language, and mutual intelligibility is only one factor among others that are used to define language.
