Io has a molten interior but nothing like plate tectonics, magma pretty much just erupts straight upwards through the crust across the surface.

Several other moons like Europa, Enceladus, and maybe Titan are expect to have something like tectonic plates and maybe subduction in their icy crusts, but in detail it wouldn't be quite the same as what we see on Earth, in large part because it's occuring in ice and water rather than rock.
