Of course. For instance when you have an embedded controller with limited ROM size and you run out of space, compressing the message strings that are sent to a till roll printer or display might be the only way you can get enough space to add a feature. I had to do this in the early '80s. The alternative was scrapping the boards and redesigning them to allow double the EPROM size but that would have been a lot more costly than writing the decompression routine and manually compressing the strings. It would also have delayed delivery.
