No it's not my test. It's from an Albanian. Many Albanian gets similar results. It is a common story that the Albanians that report probable relatives from Peloponnese will also report the same about South Albania border region of Korytsa or Aylwna , where the bulk of the Greek community lives, and the northernmost region of Skoder. And that irrespective if they come form south Albanian or Kosovo or Fyrom.
The average admixtures of the regions, or the admixtures of the users from those regions match. Here are few more.

Alternatively , if there is a more in depth analyses by 23&me, you may have ancestry from the Muslim Muhajirs kicked out of Peloponnese in the early 1800s. As in everywhere else in the Ottoman Empire, the muslims of a region were mainly of local stock .Those Muslims from Peloponnese would resettle further north and eventually many found their way to the Albanian Muslim areas, which were the last areas of the Ottoman empire to declare their independence. Muslims of Peloponnese were few tens of thousands at the start of the revolution and they had to have resettled to some other region. They didn't disappeared. It is also completely natural to have moved to Albanian speaking areas as they were mixed with Turkoalbanians sent in the regions in the 18th century.In fact we know that they did.
What you seem to suggesting on the other hand it doesn't seem to be very likely for many reasons.
For starters even if they were true the way you envisioned them, they wouldn't be recent migrations.
