Can it hurt our brand to use our logo as a (floating action) button?

We're exploring ways to familiarize our users with our brand and one idea is to use the logo as the icon in a floating action button in our mobile application views.

I have heard in the past from UX and brand people that using your brand this way can dilute your brand and/or confuse your users.

Do folkx here think that using a company logo as an action button is harmful (or beneficial) to a brand?
