I'd be inclined to say no, Im looking for the answer myself. But if you have Cov(A-B,A+B)=Cov(A,A)-Cov(B,B)-Cov(B,A)+Cov(A,B), then the last two will cancel but if Var(B)>Var(A) then we would get a negative covariance. [Cov(A,A)=Var(A)] So it looks possible because as far as I know there is no squaring of the coefficeients when you bring them out of the covariance so a negative answer is entirely possible.

Suppose that you have simple two variable model:
Y=b0+b1X1+e
The least squares estimator for the slope coefficient, b1 can be obtained with
b1=cov(X1,Y)/var(X1)
the intercept term can be calculated from the means of X1 and Y
b0=mean(Y)-b1*mean(X1)
In a larger model, Y=b0+b1X1+b2X2+e
the estimator for b1 can be found with
b1=(cov(X1,Y)var(X2)-cov(X2,Y)cov(X1,X2))/(var(X1)var(X2)-cov(X1,X2)2)
to find b2, simply swap the X1 and X2 terms in the above to get
b2=(cov(X2,Y)var(X1)-cov(X1,Y)cov(X1,X2))/(var(X1)var(X2)-cov(X1,X2)2)
Find the intercept with
b0=mean(Y)-b1*mean(X1)-b2*mean(X2)
Beyond two regressors, it just gets ugly.
