Generally speaking, no.  The environment of each process is private to
that process, allocated by the operating system at the time the process
is forked.

If desperate enough, you could set up something using the zsh/tcp module
to have your shells cooperatively swap new environment strings around.
One shell (or an external daeamon of some kind -- condsider the model
used by ssh-agent) would have to control the "master" environment, and
hand out changes to the other shells on request.  The other shells would
check at opportune times (during precmd for example) whether changes are
available, and apply them.
