Can you play Anno 1800 on a laptop (with reasonable FPS)?
Logically depends on the components.
Probably not on a 500 euro all-rounder. On a 1500 euro gaming laptop with the corresponding performance, then already.
A normal office laptop
Probably not. You wrote office laptop.
I run Anno 1800 with about 20 FPS on an Athlon 200ge with Vega 3. So it's not really fun.
A real quad core with at least 2.0 Ghz base clock from Intel Skylake / Ryzen 4x00, or approx. 2.5 Ghz for Ryzen 5-2500U / 3500U, or Intel Core i7-4xx0 HQ should be on the CPU base.
Graphics card not under GTX 960m / GTX 1050 (Ti) "mobile" or Radeon RX 560m, if you want to play in 1080p.
8 GB RAM in addition.
The bigger your settlement gets, the more the hardware is stressed. It is correspondingly slower when scrolling and the frequency of the stops in the graphic.
