No. Coyotes and wolves are NOT the same species. One can easily distinguish between them - they are (almost always) separate breeding population - they have distinct characteristics and non-overlaping prey specificity.

Tigers and Lions can reproduce fertile offspring. Tigers and Lions are also separate species.

The list can go on and on.

Some fine person has provided us the appropriate weasel words at Wiki:

"Currently, the domestic dog is listed as a subspecies of Canis lupus, C. l. familiaris, and the Dingo (also considered a domestic dog) as C. l. dingo, provisionally a separate subspecies from C. l. familiaris; the Red Wolf, Eastern Canadian Wolf, and Indian Wolf are recognized as subspecies.[1]

Many sources list the domestic dog as Canis familiaris, but others, including the Smithsonian Institution and the American Society of Mammalogists, more precisely list it as a subspecies of C. l. familiaris; the Red Wolf, Eastern Canadian Wolf, and Indian Wolf may or may not be separate species; the Dingo has been in the past variously classified as Canis dingo, Canis familiaris dingo and Canis lupus familiaris dingo."

They are regularly mated together ~ all of them ~ much to the distress of their owners who imagine them to be different species.

It is all a matter of definition and scientists disagree. For some if animals can interbreed naturally and produce fertile offspring then there is there only one species. For others any distinct population is a separate species and it is terrible when they interbreed and mess up the charts.
