Yes, as it's more often than not used. It's basically "what evolved as Christiatity, through the adoption of Judean-originating ways of belief" (as opposed to pagan ones).

"Judeo-Christianity here just means Old+New testament. They just didn't use that terminology back then, but the notion was very much the same".

The didn't say "Old+New testament" but it meant exactly that, what scholars for a couple of centuries now refer to as "judeo-christian".
