Yes, Chances are high that this will work. Zerotier does its best to connect the Devices directly but that may fail in double or triple nat Szenarios. Still it should work because zerotier servers will relay the traffic in this case, but it might be a bit slower. Give it a try!
I am also having double nat in my Office, still I am lucky and all my Devices can connect directly without relay. Everything works super fast.
