To add some closure to this ticket:
Lenovo support had to visit me 3 times:
- first they replaced the SSD -> same problem
- then they replaced the SSD adapter and cable -> same problem
- lastly they just replaced the whole motherboard -> fixed the problem for
Windows
So it seems I definitely had
Had the same problem in Windows (I think, harder to diagnose on Windows), even
after installing updates for BIOS, firmware & drivers, so this is probably a
hardware problem.
Lenovo support should visit me soon to fix the problem (with new hardware),
I'll give an update after that.

I'm starting to think it isn't a software issue.
I tried to solve it again because it was becoming impossible to work, and
decided to install Ubuntu MATE 16.4.3 LTS (kernel 4.10.0-42-generic) because I
read some people had less problems with NVMe drives on that.
The problem persisted however.

I tried it and it worked for 1 day, but it just happened again.
Maybe this isn't a problem with Ubuntu/Linux after all?
I have already checked the physical connection of the drive and as far as I
could find out the drive itself is healthy too, so I have no idea what the
problem might be...
Any
Hmm, wondering if kernel parameter "pcie_port_pm=off" helps?

No, it just had the best result out of everything I have tried. It still hangs
occasionally, especially after a cold boot.
The kernel from #13 is comparable so far: ~2 hangups per day, mostly after cold
boot.

So when you use "nvme_core.default_ps_max_latency_us=250", the issue is
completely gone?

First I want to say thanks again for all the help!

Can you attach output of `nvme get-feature -f 0x0c -H /dev/nvme0` with

Also `sudo lspci -vvv`.

As I said in the "What have I tried"-section (sorry if it got lost in

that and yes I have the same problem. It seems to be worse actually when
I put 0 as latency.

Can you try "nvme_core.default_ps_max_latency_us=1500"? This will
disable ps4, which causes lots of troubles.

Well...
Seconds after my previous message it happened again.
So it seems the upstream kernel does not fix the problem.
I'm adding GRUB_CMDLINE_LINUX_DEFAULT="nvme_core.default_ps_max_latency_us=250"
again.
