Advice please

The past 2 years when I have grown cucumber they have been in pots and  placed in the back right hand corner of the greenhouse, the greenhouse runs north - south, so that position is slightly shaded but having altered my benches I can no longer grow them there, so would there be any problems if I grow them in the same bed as the tomatoes, this bed is on the left hand (West) side of the greenhouse and full sun, when it's out, growing outside is not an option.
