The answer for your question is 'no'.
You're never going to reduce power usage substantially by swapping PSUs, because there's just not enough efficiency gains to be had even if a Pico PSU was more efficient which they really aren't.
You say the hardware is 'nothing too different' but you mention ddr4 vs 3, which makes me think the Dell is a generation or few older which could easily impact power draw by 10w.
They both have (almost) the same CPU, just once in the T variant.
The T variant is the low-power, lower clocked (3.2ghz vs 2.5ghz) almost half the TDP (65w vs 35w) variant; kinda the whole point is it's going to use less power.
The T variant is for thermally constrained systems. May not use less power, for example if a non-T completes a task faster and goes to idle
