No.  Binding and setting a variable are fundamentally different things
and not interchangeable.  While there is a small bit of overlap in
current Emacs (because of its dynamic binding implementation), with
regard to language idioms the concepts are clearly separate, and with a
lexically binding Lisp variant (which we might get some day) the
semantics are even more separated.
