AGM = Absorbed glass mat
It is nothing special and quite common they are slightly safer than the old wet battery. At the end of the day they are still just a lead acid battery and as long as they are treated as such there should be no problem and do not mix 12v and 24v chargers/boost packs.
The newer lithium battery options are the ones that i would be more worried about jumping but i expect even those would be fine like the lead acid.
The current for starting is being pulled from the jump pack and not through the battery.
