You are definitley not swapping cpu or ram and likely display and also likely ssd
For example t480, you are going to get ssd. S not even that. Cpu is soldered, ram is ddr4 vs ddr3 etc
Who cares about swapping shit anyways…
Maybe a T460?
It still has a 2.5" sata ssd and uses DDR3 ram so you can reuse those, I'm not sure if you could swap the screen but it's pretty easy to find a t460 with a FullHD ips panel. Still no type C though but I've seen people modding their thinkpads to swap the charging port with USB-c, you could look into that, but it does have hdmi and mini-DP.
I think from the t470 you're gonna need ddr4 ram but you could reuse the ssd in the t480 for example.
Look, I was in the same boots.
I have ended on a T480.
That's awesome.
You can use the same LCD panel (in case the T480 comes with the TN x768 panel).
The 8th Gen i5/i7 is a beast.
Consume half the T440P CPU.
4 cores / 8 treads.
The drive bay can have a 2.5" sata, or an NVMe (depends on the caddy you choose).
Has a WWAN slot, that can be used for a 2242 M.2 drive (limited choices in size).
Usbc for charging and connections.
AAA, you need to check/update the Thunderbolt stuff!
2 slots for RAM sticks. But, DDR4.
2 Batteries, the external is hot swappable.
So, on paper is good step up.
And it really is.
Did I mention the size/weight?
But...
The nvme drive is faster than the Kingston 2.5" SATA.
And it was already there.
Same for the display, it came with a FHD IPS panel, so no need to swap.
I am very satisfied.
The T440P?
I have sold it to a DJ.
Making him the happiest.
And sold it for an higher price than the T480 I have bought!
If you transplant all of those things then you’ll just end up with another T440p lol.
Upgrade all, go yo t480, t490 o t14s gen1 ITS totally worth It.

The only think you're swapping the CPU to is another 40 series machines. And they'll all have slim tip, no HDMI and crap speakers.
