This is not a good idea. When you loosen the oil filter there is a good chance that the rubber gasket will be displaced. I am not talking about it sticking to the engine case, which is also possible. But if you remove an oil filter and look closely at the gasket, it is common for it to be pulled out of position with the type of O-ring like gasket on Honda OEM filters. Rather than loosen it, remove the filter altogether and pour out the oil and then closely examine the gasket before you re-install the filter. Then restart the engine, and turn it off and let the bike sit for 15 minutes and check the oil window.
