No.
Although the term does appear in Norse mythology, the very specific item that was the starting point for Tolkien was the Old English poem Crist; particularly these lines:
Eala Earendel engla beorhtast
Ofer middangeard monnum sended
This translates as:
Hail Earendel brightest of angels
Above Middle-earth sent unto men
This is noted as the source in Letter 297, confirmed in HoME 2 and 9, and in fact Quenya Aiya Eärendil, elenion ancalima! (which Frodo uses in Shelob's Lair) is just a translation of the first line.
The name - or more specifically Tolkien's use of the name - therefore does not come from Norse mythology but from Old English religious poetry.
