I don't think so. The article links to an image of the 1930 journal article – https://gallica.bnf.fr/ark:/12148/btv1b53180372w – it doesn't look like it has been republished, it looks like something close to the original publication

I don't completely know what is going on here, but I guess it is something like this: the institute has since 1898 officially been called Institut français d'archéologie orientale, and its journal has always officially been called Bulletin de l'Institut français d'archéologie orientale. However, historically, people would sometimes add du Caire (in Cairo) to the institute's name (to specify its location) – this habit was supported by the history that, prior to 1898, the institute (or its predecessor) was called École française du Caire (French School of Cairo) – and then unofficially abbreviate it from Institut français d'archéologie orientale du Caire to Institut français d'archéologie du Caire or even Institut français du Caire. And since the journal is named for the institution, once people got in the habit of unofficially abbreviating the name of the institution, they applied the same habit to the journal.

So Bulletin de l’Institut français d’archéologie orientale has always been the official name of the journal, but Bulletin de l’Institut français du Caire is a historical unofficial alternative name.

As I said, I'm just speculating, I don't really know. But this seems more plausible to me than the journal or institute changing its name, because I can't find any evidence of any name change since 1898, which was long before the publication of the 1930 article.
