I you're talking about removing hard-to-get tree branches that you can't reach, then a remote-controlled might be good, but mechanically actuated cutting is still like all of the rest of the cromagnon talk you see about just TOTALLY out-of-date stuff, here.
Instead of using a chain saw, you might be able to use something called a MASER which emits a concentrated beam of microwave energy. So its different from a laser which emits a highly concentrated beam of light that can help with cutting, joining, fashioning, etc...

My MASER is in the shop, but a drone chainsaw reminds me of the part

in the Superman movie from arounnd 1970. Lois is falls or is pushed
off the edge of a tall building and she's falling, of course, and
Superman swoops over, grabs her, and says, "Don't worry. I've got
you." Lois looks around and says "Who's got you!"
When the chain saw chain hits the branch, the chainsaw/drone will be
flung forward before it can cut anything. I think that applies to the
one in the url above, and nothing in it shows that they actually cut
anything. To have a chain saw fixed in position enought to cut, you'd
need a drone the size of a small car. Maybe a big tree service
could afford one. They'd need a big flatbed truck to carry it.

then set it off from a safe distance.

Strange how someone with enough knowledge to modify/construct and balance a drone large enough to lift a chain saw wouldn't understand this.

At best if the chain were removed it would make a terrifying prop or gag to scare the beejeezus out of someone.

My impression was that their goal was to make an entertaining video and
not an actually-functional tree-trimming device.

Sigh. Breaking off icicles and decapitating snow men is easy. The
motor doesn't even need to be running. Simple inertial will do the
job.
However, if one tried to cut a limb or trunk with the saw, with
nothing holding onto the saw, it will immediately be launched in the
direction of the tree. It could be done by jamming the log between
the chain and the felling dog (spikes), but maneuvering the octocopter
to provide the rotating motion necessary to complete the cut is in my
never humble opinion extremely difficult. If you disagree, try
suspending a chain saw from a collection of strings, as with a puppet,
and try it yourself. The experience should be similar to the
octocopter at much lower cost.
Incidentally, I looked up the load capacity of a similar octocopter
and found that it will lift 50 lbs, which is well above the weight of
a similar small chain saw.
