You can, but you would have to do it through scripting which would rely on whatever methodology you’re using not breaking with browser updates and standards changes, whether or not the user has scripting enabled to begin with, whether not their adblockers or other plugins mess it up, etc. And then you can wind up just deferring the issue. Let’s say the user intends to quickly skim through your page to see if it actually appears to contain what they’re looking for or whether it’s just SEO bullshit, so they scroll down right after the first chunk loads and hit the point where the next chunk should load, and unexpectedly find that it didn’t do so instantly (because it probably won’t) and it appears your content cut off mid-page. They’ll assume your site is just broken and you’ve never seen another user hit that back button so fast.

So the answer is “yes, but,” and may not be worth the trouble.

Clicking a “continue reading” button is not an ideal solution either, but at least the user will (should) realize that they’ve performed an action that will load more content, as opposed to having it happen behind their backs in a manner that they weren’t initially aware.
