[Elder Scrolls] If the Third Empire had Dragonborn as a criteria as being the heir, does that mean that the Last Dragonborn can claim the Empire as its Emperor after the death of Titus Mede II?

No. The legitimacy of the Dragonborn Emperors dates to Alessia, and the First Empire, it's not something related specifically to the Third Empire. It is, instead, a mandate to rule as part of a divine contract with Akatosh, referred to as the Covenant of St. Alessia. 

That Covenant ended with Martin when he mantled Akatosh and drove out Mehrunes Dagon during the Oblivion Crisis (the events of Oblivion). The Dragonborn Emperors no longer have their Divine Mandate, and no longer have any claim to the throne of the Empire.
