Is this possible...I have an octagon window approximately 20" across.
It's dual pane and has lost its seal so there is moisture inside. *Would
it be possible to pull off the interior wood trim and somehow remove the
glass and replace it w/o removing the entire frame?

That would be the normal method.

Have something ready to fill the opening once you remove the old
window, it may take a week or two for a local glass shop to take the
old window and send it out to have a new one made up. Most local
shops outsource thermopane style glass fabrications.
