Yes you can use but first you need to conduct atmospheric and geometric correction to your both images.

Good Morning. Landsat images legacy, are designed for interoperable use between them. But the MSS and ETM + sensor are different in several respects. (Asusencia of the Blue band, spatial resolution, etc.) On some older items a Prosesa approval among these images are presented. Especially in later articles to the launching stage of Landsat 4
DrOmar Pelaez-Martinez Thank you, professor of this means that the Landsat imagesMSS and ETM used alone without mixing them ..??
I disagree on the need for atmospheric corrections, but otherwise see attached.

Dr Hein Van Gils thank you our prf
We've all corrections
Can a spatial change detection between MMS/TM/ETM
I agree with Dr Hein Van Gils on the fact that atmospheric corrections are not necessary all times. It depends on the objective of your study and on the methodology you follow.
If you only want to quantify the changes in a general way, you can classify each image separately (processing it as well as you could and quantifying the errors) then by knowing the area covered by each land use in each date you can quantify the changes between them.
In the case you want to compare both images pixel by pixel you should perform a geometric correction and may be a relative radiometric normalization will be necessary.
