Most aircraft can land at MTOW, it took off at MTOW and the gear didn't collapse so one would assume a soft landing at MTOW would be fine as well, there is also increased compression on the mains as the tail force rotates the aircraft to climb attitude. As for whether no damage is done, depends on what you call damage, might simply add 100 landings to the gear cycles, which damages the bank balance in the long run in addition to an overweight landing inspection. Abonormals that exceed limits generally are allowed for by adding cycles/hours to the part as if it had worn more in some cases.
The point being the company should advise what they want crew to do unless it's plainly obvious. In most aircraft I've flown the checklists direct you to land at the nearest suitable airport. Only emergencies like fire dictate a landing ASAP.
