30 amp 240v circuit with 120v outlet.

Let's say I need a 240v circuit. I run 10-3 to my 240v receptacle. Can I then install a 120v receptacle using the neutral wire one one of the hots from the 10-3?

In theory, yes. In practicality, no. You have 30 amp OCP, which will be too much for the 120 volt receptacle, and it would be a bear bending 10 gauge wire inside a box and connect it to the receptacle.

Though not recommending it you could use a fused receptacle with a 15 amp fuse and probably meet code.

Who said he's not using a 30A 120V receptacle?

Assuming you use a 30A receptacle, you can do that no problem.

True, but walk around your house and write down the number of 30 amp 120 volt receptacles you have. Or the practical applications.
