No, I doubt an eagle would even try, much less, have the ability to kill a coyote. A mature golden eagle, weighs give or take a little, 12 pounds,and a mature coyote averages 25 pounds. An eagle has a tough time taking off with a jackrabbit in its mitts, much less tackling a coyote.
The eagle doesn't have to take off with it and raptors frequently kill prey larger than themselves. I had a 500 g. (1 lb) male prairie/peregrine falcon that would routinely cut thru a flock of ducks and take the lead drake mallard. That same tiercel took 3 full grown jackrabbits (this was his prairie blood talking) and bound to a full-grown Canada goose but lost that one before we could get there. Out in Idaho, I had a friend who caught coyotes with his golden eagle, running in a team with an Irish wolfhound. The hound would flush and push the 'yote, and the eagle would take it down from a soar or off a nearby cliff. Doesn't have to kill it- as long as it can hold the coyote down, the falconer can do the killing. Trained raptors know this and will bind and hold to prey much bigger than they'd normally take by themselves.
In the wild, if you have a pair of goldens working together, they can kill some pretty large prey. I'm not saying they'll do it regularly, but a hungry eagle is a ferocious bird. Twice here on the ranch, I've found freshly dead and partially-eaten pronghorn with hair and golden eagle body feathers strewn together for 20 yards in a zig-zag line. Quarter mile away were my resident eagles with huge crops. There's no question that they ate the pronghorn and the feathers mixed in with the antelope hair looked just like the aftermath of a Harris' hawk taking down a jack. I have case after case of other biologists seeing similar things- one of them was counting 'lopes from a helicopter when a golden came in underneath them, bound to a yearling 'lope and took it down. My ex-boss called me up last year wondering if I could say anything to eagle/pronghorn interactions for a book he was editing. So, the evidence is there.
What you're seeing in that video sure looks like Mongolian eagle hunters. They've been doing this kind of thing for a long time- it's how they collect furs for sale. Couple of links:

That dog that jumps on the horse is probably a chase dog just like my friend's Irish wolfhound was. Surprisingly, eagles (and other trained raptors) can work with such things and not take them. Some guys use small dogs like Jack Russell terriers to push rabbits and others use ferrets, and the hawk doesn't take them.
The eagle-cam is WAY cool!!
