Such bombs have been successfully disarmed (and that one appears to be more complicated). The time to disarm may not have been available though:

Police defuse necklace bomb

Police have disarmed a collar bomb placed around the neck of a Venezuelan man by Colombian rebels trying to extort money from him.

It took several hours for Colombian and Venezuelan secret agents to disarm the bomb around the neck of Jesus Orlando Guerrero, 65, a ranch owner from the western frontier state of Tachira.

Three armed men forced the bomb around Guerrero's neck on Monday night, attacking him on his cattle ranch six miles from the Colombian border.

The attackers threatened to detonate the bomb in 72 hours unless they received the equivalent of £113,000.

The bomb was constructed out of a galvanised tube filled with C-4 explosives. It was painted gold with the words FARC-EP, an acronym standing for the Revolutionary Armed Forces of Colombia, Colombia's largest rebel army.

The time to disarm was definitely not available, since the bomb squad - the only people who MIGHT have the expertise to disarm the thing - hadn't arrived before it went off.
