After reading my own documentation ;-) my answer is yes. You can let the 
tagcloud read the id's and then use the "postProcessRawKeywords" hook. 
In this hook you receive a list of all keywords found, i.e. in your case 
all id's. You can then query your categories table inside the hook and 
replace id's with the corresponding category name.

I remember someone doing something similar, but the other way round: 
matching keywords to id's of glossary entries. So you should be able to 
achieve what you want.

Cheers
