college child as dependent and latest stimulus - is there a connection?

can someone help me think through this, please? my spouse and i file jointly and we have claimed our full time college student son (currently 23) as a dependent in recent years (have not yet filed for 2020). is there any relationship between whether we claim him in 2020 and the latest stimulus and whether he would receive the $1400 aid? his income in each of the last two years was under $10K/year. he did not receive any prior stimulus. my spouse and my joint income is over $160K (so i don't believe my spouse or i would qualify for latest stimulus). so i am trying to figure out whether we should continue to claim him as a dependent or if there is an overall family benefit by NOT claiming him IF that would allow him to receive the stimulus. Or maybe one has nothing to do with the other? thank you very much for your thoughts and guidance.
