Absolutely. REST is a very simplified version of SOAP: think of it as just sending and receiving a document via a socket, using HTTP as the protocol. The biggest issue is the formatting of the data. Whereas SOAP uses XML almost entirely, many REST services use JSON, which is (typically) lighter and faster.

Note that pretty much all rich UI mechanisms are moving away from SOAP and towards REST. You use REST when you're sending a small message especially when you have control over both sides of the conversation (think client/server), while SOAP is more for large transactions with outside vendors (think EDI).
