Dysregulated oxalate metabolism is claimed to be just a dysfunctional metabolic pathway that leads to excess of oxalates.
Warburg effect is a bit different. While the author Otto Warburg believed that cancer cells preferred anaerobic (oxygen-less) glycolysis pathway, the modern view on this topic has evolved. Now we tend to believe that cancer cells maximize and exhaust all energy sources available to them. This includes a normal aerobic pathway. Once the mitochondria is stressed out and broken, it no longer is able to support the adequate levels of aerobic glycolysis. The host cell begins to starve in ATP and this is where the anaerobic pathway kicks in. So it is not that a cell has a specific preference; it is just a matter of survival and chemical auto-regulation.
So no, Warburg effect is not really a cousin as far as I can see.
