Under no circumstance give the VM more than 1GB of RAM and 1 vCPU.
Then it is possible, but performance probably won't be great.
- the lack of sufficient RAM
- the external USB disk, which likely is going to be pretty slow depending on the disk you put in there. If it's an SSD then it is probably OK, if OTOH it is a 4200rpm/5400rpm disk then don't expect too much from it.

I wish they'd stop selling win10 laptops with 4gb, with the average browser using 1gb-2gb of memory, and windows using more on its own the performance in the host os is going to be bad enough. In addition to what wila said, I'd recommend not trying to do things both in the host os and the vm at the same time, it will probably so slow. If your somewhat familar with the windows os, you could follow something like
to disable some of windows default services, but I'd be aware of what your disabling, and only disable a service if you understand what it does.. I did this for my laptops before I made enough to put as much memory in them as possible.
