Yes. What you are looking for is 'org-hd-marker property. It holds
marker to the position of the corresponding headline.

Once you know the marker, you can simply

(org-entry-get marker "CUSTOM")

It does not matter that current buffer is not the Org buffer. Marker
contains buffer information.

Best,
