Yes. Any medium that can transmit information can be used to communicate. Doesn't even need electricity. Sea water can transmit electricity (poorly), sound and light, all of which can be used to transmit information. With a proper sending and receiving unit at each end, that information can be encoded and decoded into usable data.
You'd have all kinds of reliability issues, but it could be done. In fact, it's being done right now. The US navy uses very low subsonic frequencies to communicate with its nuclear ballistic missle submarines. They can hear and translate that signal from anywhere on the planet, even deep undersea.

Interesting question. Seawater is highly conductive due to the high number of ionic impurities. So, it is possible to get it to conduct a current. I suppose, in theory, a tube of it could be used as a "cable" for a single signal. However, it would have quite a voltage drop across it making need for signal amplification.
I suppose a better question is, why would one want to? There are much more practical ways to do it.

Please don't, it's not good for the wildlife in the sea.
Like, active sonar will kill whales and dolphins.
