Sadly no, because everything is closely tied to the node. For example, it might take 0.3ns for a signal to physically travel from one edge of the chip to the other on a 7nm chip. On 12nm, it might take 0.5ns. The chip was designed to compensate for a 0.3ns delay, not 0.5, so now the cache is sending data to the core at the wrong time, leading to corruption and garbage data being processed. This, plus a million other things in both manufacturing and design have to change to build a chip on a different node (manufacturing tolerances, clock speed, metallurgy, patterning issues, etc.).
