I personally think you'll be able to manage it but what you should do is see if you can find anyone else with the same model laptop or the same mobile GPU with an equivalent CPU and see how their experiences in VR are. 
Unfortunately you may have to go to rebbit to do that, sorry. 

With regards to your 1650m, it's pretty much a 1050ti and the 1050ti did me just fine in VR for two years, with a far weaker CPU attached to it.
