Could you do jump rope if you were to just go slow during the 10 second rest so you can immediately go as hard as possible for the 20 seconds?
That would be jump rope intervals. Not bad, but not Tabata. Also, I'd say that jumping rope fast for 20 seconds straight without tripping is a rare skill by itself.
Chad Waterbury has describe Tabatas:
"imagine you find yourself on some rail track and you hear the sound of train coming up behind you, you turn around and see a freight train thundering towards you... your only option to run, and run hard. You try to out run the train for 20 seconds and just as it is about to hit, you jump off the tracks onto another rail track.
Your lungs are bursting and your muscles are screaming at you but after just 10 seconds you hear another train coming and you have to run for your life again!!! That is the intensity - and guess what, you get chased by a total of 8 trains meaning you are running for your life for 4 minutes."
