Should be fine - Shimano is always conservative when it gives largest-ciog figures. You'll most likely need a new chain, and may have to adjust the B-screw in (to make sure the cage clears the large cog)

*I just looked and it seems the smallest big cog you can get is a 32t, this means it will probably not work as that is too big.
Still could be worth a try but I doubt that will work.

The cassette will physically fit on the freehub and there shouldn't be any compatibility problems, as long as the derailleur has enough movement to clear the largest cog- depends on the ratios of the cassette and the derailleur length.
If it will shift into every gear without binding, letting chain hang loose or stretching the derailleur too far it will be fine to ride.
