If you check out device datasheet you will find that the integrated converter samples data with speed of 200-ksps. Therefore you should be able to capture 4kHz signal without a problem.

Short answer: yes.
Long answer: sampling rate depends on ADC clock frequency (default: 6MHz), clock divider (1..10), sampling time (4,8,16 or 64 clock cycles) and conversion time (13 clock cycles). Precise frequencies can be achieved by starting each conversion individually, by hardware (a timer trigger) or software. 4kHz are no problem with any method.
