Isn't the spin only a synonym for the existence of a magnetic dipole moment and its direction?

Question

For this question What does the magnetic moment of a quantum particle depend on? was given such statement:

The magnetic moment of ... an electron, is intrinsic, and related to spin.

Isn't the spin only a synonym for the existence of a magnetic dipole moment and its direction?

Answer 1

No. The spin of quantum particles is indeed an angular momentum, and it can be changed over into orbital angular momentum if the circumstances are right. The Einstein-de Haas effect is the canonical example of this.
