You can use apply to pass a list as the rest arguments:
(setf args '("1" "2" "3'))
(apply (function call-process-region)
start end program delete buffer display args)
You can also put some or all previous arguments in the list too:
(setf args (list start end program delete buffer display "1" "2" "3'))
(apply (function call-process-region) args)
