Kimi:
I think this is more a question about how Twitter's lead generation card works. I believe you can put the landing page as the Fallback URL in Twitter, and you could have that Fallback URL be a Marketo landing page, but I don't think that's not exactly where the button goes. On supported device/app, it goes to a "Thank you for your interest! [Company name] will be in touch soon. <Learn more>" with the <Learn more> being a link to that fallback URL.
Does that answer your question?
(If you want to get super fancy, you could call a webhook upon lead creation in the Twitter campaigns, which could automatically Follow the new lead on Twitter [via their REST API], and send a DM if the lead is already following you in the first place.)
