No,copper cannot be used.
Copper is below hydrogen in the reactive series and will not displace it from an acid or water. For this reason, copper cannot generate hydrogen by reaction with dilute acids.

Answer:
No
Explanation:
In the reactivity series, Copper is placed below Hydrogen which implies Copper is less reactive than Hydrogen.
We know that, Metals displace Metal Salt from Dilute acids only if the metals are more reactive than the acid's salt.
In this case, Copper is less reactive than dilute acids, due to which it wont displace Hydrogen from acids.
Therefore the reaction would be:
Cu + HX ⇒ No reaction [ X refers to Halogens ]
