Hi,
It may be possible.
Here’s a link to the [http://h10032.www1.hp.com/ctg/Manual/c05219193|service manual] for your laptop, taken from this [https://support.hp.com/us-en/product/hp-pavilion-m1-u000-x360-convertible-pc/10862146/model/11084072/manuals|webpage]
Scroll to p.49 to view the necessary pre-requisite steps and then the procedure to remove/replace the memory module.
Also on p.49 you’ll find a list of the compatible memory modules (dependent on the CPU) and the HP part numbers for the modules.
Hopefully this is of some help.
