You know you can, of course. But what you are communicating is
information derived from your 'seeing a square' in order for others to
instantiate something analogous, as 1-person experiences of their own.
Your 1-person experience per se is incommunicable, and consequently you
have no direct evidence of (although you may be jusified in your
beliefs concerning) what others have instantiated as a result of your
communication.
