ADAU1466 vs. ADAU1462 Code Compatibility

I currently have several designs running well on ADAU1466-300. Assuming the data and program memory usage is below the limit of ADAU1462-300, can I use the ADAU1466-300 generated code and load directly onto ADAU1462-300 without any changes? Or does the code need to be re-compiled for ADAU1462-300?
