Yes, possible.

As condition use a formula:
=ISERROR(MATCH(A1,listrange,0))

Above example assumes that you have a named range 'listrange' that holds
your separate list of names (of course you could also use something like
$B1$:$B$10) and that your cell containing the conditional format is A1. This
will format all cell entries in A1 that are NOT in the specified list.

I would like to apply a conditional format into a cell, so that when I type
a
name into that cell, if it doesn't exist on a separate list of names, the
condition will apply. Is it possible?
