That is not a problem at all, but keep in mind the
icon-buttons section in footer is specifically designed for a single icon (font-awesome font icon) without text. If you want to add text and images into an "icon-button", it will look strange (like in your screenshot). Normally, you would add custom text/image links BELOW the icon-buttons ... Why not just add your Microsoft text/image below footer-icons instead of trying to get the icon-buttons to do something they are not for? Feel free to proceed as you wish, if you think it works inside an icon-button.

Only with
custom CSS, although it seems a bit unproductive to nullify the design of the icon-buttons, then why use them in the first place?
.icon-buttons a {
background: none !important;
}
