"All the newfound moons are small, between about 1 and 3 kilometres across. Seven of them travel in remote orbits more than 20 million kilometres away from Jupiter"
As a layman with no astronomical credibilty I'd call those satellites, not moons.

"Natural satellite" is a subset of "satellite", thus what you'd call them is correct by definition. Let's let the astronomers with credibility play and name the objects.
Slightly related, are all the particles in (eg) Saturn's rings wver referred to as moons?
So as it stands, a moon is simply any natural body in orbit around a planet or other non-stellar object (so asteroids can have moons, and it’s even possible for a moon to have its own moon, although none have been discovered so far).
But moon anyway mostly just means natural satellite.
