Be careful of pinouts is about the only thing that I can offer. The 29C256 is a 32Kx8 Flash. 
Once programmed the CPU sees it as a memory and is not particular as to what type it is. 
The speed grade is 90nS so it is far faster than needed on any COCO. 

IF the pinouts match what is currently on board then you should have little or no problems. 
The voltage ratings are the same so have at it.
