Its very unlikely to be satisfactory, as the laptop PSU you linked to has a two pin mains input, but as it isn't a medical grade PSU, will have a significant Y capacitor leakage current. In most countries, regulations limit the leakage current to 0.75mA, and the typical leakage current is usually over 1/3 of that. The result will be a line frequency common mode voltage on your PSU output of approximately half your mains supply voltage, with approximately half a mA 'drive' behind it, which is more than enough to almost instantly destroy MOSFETs and other highly ESD sensitive devices, simply by touching their gate terminal with a grounded soldering iron bit without either fully disconnecting the PSU from your circuit, or the PSU from the wall socket.
A three pin input grounded output laptop charger wouldn't have the Y capacitor leakage current problem, but a bench PSU with a grounded output is a PITA, and if interconnected with high current loads and an Arduino with USB connection to a PC, you can easily end up with significant ground loop currents, risking a blown PC motherboard.
Its possible to mod a floating output open frame PSU, replacing the Y capacitor with two in series with the intermediate node grounded via a choke, to virtually eliminate line frequency leakage current without significantly degrading its EMI performance, but obviously that's not an option for a sealed laptop charger with a two pin input.
Other options are a floating output medical grade (low leakage current) PSU, which will usually use a grounded inter-winding screen to eliminate leakage current without the need for a Y capacitor, or an 'old-skool' line frequency transformer + bridge rectifier + resevoir capacitor PSU. You'll need a 22V 300VA transformer with 10% or better regulation to get full output from the DPH3205, which wont be particularly cheap. A lower voltage or lower VA transformer either wont be able to deliver full output or will overheat on sustained full output. A higher voltage or worse regulation transformer will over-voltage (and possibly destroy) the DPH3205 during low load operation if the mains supply rises towards the upper end of its tolerance range.
