Not as such. A sight glass is just a viewing port. However, alot of sight glasses also have a moisture indicator in them in the form of either an outer ring or central dot that changes colour.

You posted pictures in another forum so I know you are referring to the typical liquid line sight glasses we use.
A sight glass shows the state of the refrigerant in the system.
So yes, some call it a liquid indicator because that's the state of the refrigerant we want to see in the liquid line after the receiver.
Then as ka2424 stated, it's not always a moisture indicator.

Though my English is not too good, I'd say sight glasses are a subset of liquid indicators.
They could be synonyms for someone that works in air conditioning, domestic or commercial refrigeration but not for someone working in industrial refrigeration.
