@svermaak,
I’ve tested the same scenario in a multi-geo SharePoint Online setup using SPFx, and I was able to successfully retrieve:
/_api/web/AllProperties
from a site in Tenant B, while running the SPFx web part in a site from Tenant A, using SPHttpClient.

Just to better understand the issue — could you please share if you're seeing a specific error message or HTTP status code when the call fails?
