Charts say yes. Nobody has tested rosemary with sage, as far as we could find. Both are in the Lamiaceae family, so they share pests and diseases.
Why we can't give a firm answer
Garden charts recommend it. 1 garden chart entry recommends growing them together. It cites no source. Charts pass on gardening tradition; they are not tests.
