To a certain extent, "yes", but in most cases that content will be limited to article blurbs that will lead visitors off your site to the original content. Most syndicated RSS content requires a link back to the source. Also, full article feeds are somewhat rare these days. Often you'll just end up with a short excerpt that would require your visitor to click through to the original site to read the full article.
