I remember hearing about this over at ResetERA about a year ago, but the thread devolved into sinophobia and got locked before anyone could really look into the claims.
If this is true at all, Larian has kept it extremely well hidden. In this case, I wouldn't be concerned about the Tencent side of things as they're pretty much everywhere nowadays, it'd be more about Larian pretending to be an indie company for the goodwill if it turns out that they're having secret acquisitions.
The only source I could find in regards to all this stems from a couple Twitter threads. Seems rather dubious to be honest.
