In theory, yes. But it only takes a minute amount of vacuum or back-pressure to make the gas go down the wrong pipe. The objective was to pressurize the hydrogen; if the pump creates a vacuum on the hydrogen pipe it will suck in the oxygen too.

Also, some oxygen is dissolved in the electrolyte and will dislodge together with the hydrogen regardless of back pressure. That last one will not normally result in dangerous oxygen levels, but saying the appliance usually does not explode is not good enough.

To do it safely the electrodes need to be separated by a sturdy and airtight membrane.
