Yes BUT only the NAted network will be able to initiate the tunnel. For Example If you use policy NAT and your network 10.10.10.0 is translated to 192.168.10.0 then your Network will be able to initiate the VPN tunnel, But the remote site for example 172.16.32.0 will not be able to reach the Network 192.168.10.0 (the 10.10.10.0 NATed).
This kind of translation is NOT bidirectional. Like a static NAT
If you try to initiate the tunnel from the PIX-B, the destination address of the VPN interesting traffic 172.18.1.0 , for example, natted network address of PIX-A, is not reachable. So you must initiate the VPN tunnel only from the PIX-A.
