The t=10, replacement (taking up 5 characters) actually makes it worse by 1 character since 10 is only used 4 times (8 characters). Dropping the tc= assignment and the t=10, replacement, you're down to 136 characters:

n=>{if(n=n.split('').map(Number),o=n[e=i=0],c=n[9],t=10,o)for(;++i<9;)eval((i%2?'e':'o')+'+=n[i]');return!((7*o-e+t)%t-c|(o+e+c)%t-n[t])}
