In this particular case, no it is not possible. For further discussion see:
Just because some closely related species can cross, doesn’t mean all can.
Also, as your link notes, the Biological Species Concept ( species as a group that can interbreed to produce fertile offspring under natural conditions ), though the most commonly cited, has many detractors and a number of exceptions. For example wolves and coyotes will interbreed to produce fertile offspring in the wild and it is likely the “Red Wolf” was one result of such crosses. They don’t commonly do so, but they can and will. Yet for a number of reasons including overall genetic distance from each other as a group ( while having in comparison far less genetic diversity, even over large geographic areas, within either species ), the restricted geographic nature of hybrid zones, the peculiar behavioral nature of such hybridization events ( almost always female coyotes with male wolves, whose offspring cross back with wolves ), and other reasons, they are still considered distinct species.
