But Frisk's body moves by itself only slightly more in Genocide than other routes, and you can back out of the route at any time, even as far in as Sans. If Chara was taking over their body, wouldn't the game basically become a cutscene as Frisk is unable to do anything? In what other way would you describe the interactions with Asgore and Flowey at the end of Genocide?

That Frisk is ceding more control to Chara as time goes on does not mean that Chara has complete control by the end of Genocide. Rather, just that Chara is able to exercise more influence than before, and more influence than in other routes. Frisk or the player, however you want to define that relationship, still has some control. It is only when the soul is sold that full control is handed over, and even then it is not entirely clear how that works.
