Yes, although siting the electrolyzer at the PV farm uses DC from the modules directly, avoiding DC-AC inversion losses, transmission losses and AC-DC rectification losses. Having the smelter there too avoids hydrogen transport and storage costs.
All that, of course, has to be balanced against ore transport and slag disposal costs.

For example a 600km DC link in NZ[1] has total losses of 1.42% on the first 323MW and 3.30% on the next 753MW[2] (age of rectification & inverter equipment varies). There is AC to DC conversion at both ends, so that is equivalent. DC transmission losses are less than an AC segment would be (220kV AC to 350kV DC with 40km underwater).
