If fit a linear regression model with one predictor (X1) but exclude a second predictor (X2) which is uncorrelated with X1, does it bias the estimated coefficient of X1?

yes, https://en.wikipedia.org/wiki/Omitted-variable_bias the model over- or underestimates the coefficient for X1 to compensate for the variation that would have been explained by X2
