Yes it's possible, but how do you know how much space is available on smaller mobiles? In your screenshot, I can't see that there is room for much increase in size, without getting too close to the menu. You could perhaps align it to the left on smaller screens? CSS:
@media screen and (max-width: 639px) {
.logo-wrapper {
text-align: left;
margin-left: 20px;
}
.logo>img {
max-width: 80vw;
}
}
I don't think it provides much benefit of scaling your logo up too much, as it's still visible and readable when smaller.
