Correct. The 190 is the 68040 and 5300 is the PowerPC of the (more or less) same laptop.
The 190 (b/w), 190C and 190CS shares the same screen with the 5300 (b/w), 5300C and 5300CS.
The 5300CE is the only laptop of the series that does not have the a 190CE counterpart.
There was a 190 68K to 5300 PPC upgrade where the motherboard is replaced with the badges. It also gave the 190 an IR port which was not available on the 190 except for as add-on option as a daughter board but was part of the motherboard on the 5300.
Throwing you a curve ball, the 2300Duo was a 5300 PPC with a smaller screen and Duo notebook motherboard but shared the 190/5300 CS active LCD screen. All three shared the same Enabler file for System 7.5.2 and all three had IDE Drives and trackpads.
