Half this crap about asbestos is a load of money making crap
Fact about asbestos is that one single particle is enough to cause lung cancer.
However, those people how actually develop this kind of lung cancer are most of the times those who have been in frequent contact with asbestos through their work, like people who work in an asbestos mine or an asbestos factory.
Nevertheless, sometimes people who have had only the briefest of contact can get it too. All people are constantly exposed to traces of asbestos, because small amounts of asbestos fibers are in the air and in other products, like your coffee. But only very rarely does this exposure lead to lung cancer.
So generally speaking, you're safe as long as you're not working with it on a daily basis. I mean, statistically speaking. But there's always the chance you end up the odd fellow out.
I'd take it on the safe side. If you suspect something contains asbestos, leave it be or have it removed professionally.
As for the money making crap, even though the general population is relatively safe, those who have to remove asbestos profesionally are not, for them asbestos is a very serious risk due to the frequent exposure. So tools geared to aid them in their line of work are the subject of very strict regulations and the highest of standards, so they inherently become expensive. A vacuum cleaner rated for asbestos is not meant for a general contractor who occasionally encounters asbestos, but for those people who work with it on a daily basis.
In that light it is only logical that a company like Festool advices people not to use their CT/CTL/CTM line of vacs for hazardous materials, even though somebody who rarely encounters asbestos, like in the case of the OP, could get away with it.
