in M0's manual, it is said that the systick is optional,does lpc4357's M0 core carry out this feature?

The M0 and the M4 *share* all the peripherals. So, you can chose to use the Systick timer in the M4 or the M0. Same with most other peripherals.

Are you sure about that, have you tried it?
The M4 Systick timer is part of the M4 core, so I would assume that the M0 cannot use it.

Yes, I am sure the peripherals are shared.
After booting, the m0 can take complete control of the system
