It isn’t misleading, Kotelniki (the place in the article) is as much a part of Moscow oblast as Khimki or Domodedovo. And people routinely just refer to those areas as Moscow all the time. Beyond that, Moscow subway transit system goes to Kotelniki as well, I just doublechecked that.

Here is an analogy that might help those familiar with the US: it is kind of like Yonkers is to NYC, Chicago suburbs are to Chicago the city, or Burbank is to Los Angeles.
