Welcome to the Lenovo Community !
The Yoga 700 model line shipped with either a 40 watt or 65 watt adapter. The Yoga 3 Pro's adapter is a 40 watt. That being said the Yoga 3 Pro's adapter will work, but if your Yoga 700 came with the 65 watt charger you will find that using the Yoga 3 Pro's adapter for the Yoga 700 may cause the adapter to get very hot in use and the battery will take longer to charge. Due to the heat issue it isn't recommended that a 40 watt adapter be used on a 65 watt system. If you do use it then only use the Yoga 3 Pro's adapter on the Yoga 700 when the laptop is shutdown.

You are good to go. The 2A is a 40 watt adapter.
