I think that it should be considered canon as as the story picks up events from Frozen and affects the story of Frozen II in some way (mostly related to Anna understanding Elsa's needs a lot better).

Anna and Elsa met a Nattmara in the book. It was modified compared to the real-life legend (Ulf the wolf instead of a woman) but still.
