Can I add a MailChimp short code to my header (in addition to my logo)?

I have a logo uploaded to my website and a few social media icons. However, there is a large blank space in the middle of my header. I’m wondering if it is possible to insert a shortcode for a MailChimp signup form there. If so, can someone tell me how to go about doing this? Thanks very much!
