You can achieve this by using a Link Block function which is the easiest method.
Set the background image to the svg, set size constraints and then set the link in the settings tab.
Alternatively, you could look at installing Font Awesome into your site and using icons. This would be my recommended route to achieve your end result as it will provide less impact on load times.
Font Awesome will allow you to select icons (including top brand logos) from a cheat sheet, paste it into a text link field, and customise it as if were text, including font size, colours effects etc.
I would recommend trying to find an install tutorial online, sadly I do not have one to hand.
