Yes. First define a SpamAssassin rule like

header FOUND_SPECIAL_HEADER  exists:Name-Of-Your-Header
describe FOUND_SPECIAL_HEADER Whatever you want to describe this
score FOUND_SPECIAL_HEADER 0.1

The score can be any non-zero value.

Then you can make a ruleset for SpamAssassin Rule Actions, e.g.

SpamAssassin Rule Actions = %rules-dir%/spam_rule_action.rules

and in that file put things like

To exempt at example.com FOUND_SPECIAL_HEADER=>deliver
>From other at example.com FOUND_SPECIAL_HEADER=>deliver
FromOrTo default FOUND_SPECIAL_HEADER=>store,discard
