The question bears the same merit as if you asked whether you can send a TCP packet from a problem written in language A to another program written in language B. The answer has to be yes, otherwise why we have all those standards.

In the case of TCP packet, the issue is how to pack and unpack the packet (to interpret it) on both side. Here the same. The precise answer is that, yes, as long as, both side interpret the SOAP packet correctly, following the same definition.
