In class, we said that Van der Waals forces and London Dispersion forces are synonymous when talking about nonpolar bonds. However, in high school chem I remember that Van der Waals encompassed a broader category which included even those with weak dipoles, so I was just wondering whether these terms are interchangeable?

I think he was referring to the strength of the bonding. In terms of strength they are relatively similar.

I believe that these attractions have minor differences, but we will consider them equal in this class.

Van Der Waals is the general term used to describe intermolecular forces between atoms which encompasses both strong dipole-dipole moments and the weaker london dispersion forces. Therefore, london dispersion is a sub category of Van Der Waals interactions.
