John Mueller received a question about possible cannibalization of keywords in subdomains and related possible ranking restrictions in Google. He replied that there are no page ranking quotas from sites on Google.
Thus, there are endless opportunities for any site to rank on Google for an infinite number of keywords.
There's no hard limit for how many pages we show from a site, subdomain or not. Regardless, from a strategic point of view, if you're competing with your own content, you're going to have a harder time against stronger competitors.
