No, all AMD mobile processors after 2013 are BGA (soldered to the motherboard), and are thus not easily upgraded.
Like @neon said Mobile CPUs are hard to replace.
However there are Laptops with desktop CPUs like the ROG-Strix-GL702ZC.
This one as example doesn't have the CPU soldered , so you could as example get
the one with R5 anc change the CPU to R7. Now 'if' ASUS decides to update the BIOS and
support Ryzen second gen you could in theory even have R7 2700 installed in it.
