Yes, it is possible, however not necessarily easy.

SOAP Web service is (usually) receiving HTTP requests with XML in the body and sending back HTTP responses with XML in the body.

REST-assured can send HTTP requests with any content, including XML. It can also verify XML in responses with GPath.

Here's an example from REST-assured site:

Imagine that a POST request to http://localhost:8080/greetXML returns:

<greeting>
   <firstName>{params("firstName")}</firstName>
   <lastName>{params("lastName")}</lastName>
</greeting>

i.e. it sends back a greeting based on the firstName and lastName parameter sent in the request. You can easily perform and verify e.g. the firstName with REST assured:

given().
         parameters("firstName", "John", "lastName", "Doe").
when().
         post("/greetXML").
then().
         body("greeting.firstName", equalTo("John")).

The problem is that SOAP Requests and SOAP Responses are usually far more complex and you will need to understand WSDL descriptors yourself.
