Absolutely...

Friction is due to molecular interaction at the surface, nobody says it has to be less than gravity. For instance, if you put some glue at the bottom of a paper box and try to move it on the floor, the friction will be larger than the weight of the box.

\({\mu}=\frac{F}{N}\)

Also, silicone rubber or acrylic rubber-coated surfaces have a coefficient of friction that can be substantially larger than 1.

I'd never heard of anything specifically so I decided to do a little digging because I was curious. According to Wikipedia (haven't verified it with any other sources) rubber-coated surfaces can have coefficients of friction that are greater than 1.
