Answer:

Yes, but the quantities would need to change

Explanation:

Start by writing out the reaction:
#CoCl_2 + NaOH -> NaCl+ Co(OH)_2#
Balance the reaction:
#CoCl_2+ 2NaOH -> 2NaCl + Co(OH)_2#

Compare this to a reaction using #Ca(OH)_2#:
#Ca(OH)_2 + CoCl_2 -> CaCl_2 + Co(OH)_2#
As you can see, only half the number of moles of the hydroxide compound is needed to bring the reaction to completion.
