Common cc/cv charger for same volt and different capacity
There is theoretically and practically. 

Theoretically if the chemistry matches then it should be fine. 

Practically there are more pitfalls than one could count. Is the battery smart? If it is smart then the internal communication to the battery may not match. If the charger is smart then it may know that it exceeded the capacity of the battery that it was designed for. This would cause the charger to shut off with the battery half charged. If the internal battery fuel gauge is smart it may be confused by the higher battery capacity. The connectors may not match. The new battery is going to be larger than the old causing space constraint problems.
