I think the Reformed tradition would locate Jesus' body "in heaven", I believe these two quotations from Reformed authors will illustrate.
From his commentary on Acts 1:9-11:
And it was needful that the history should have been set down so diligently for our cause, that we may know assuredly, that although the Son of God appear nowhere upon earth, yet doth he live in the heavens. And this seemeth to be the reason why the cloud did overshadow him, before such time as he did enter into his celestial glory; that his disciples being content with their measure might cease to inquire any further. And we are taught by them that our mind is not able to ascend so high as to take a full view of the glory of Christ; therefore, let this cloud be a mean to restrain our boldness, as was the smoke which was continually before the door of the tabernacle in the time of the law.1
From Systematic Theology:
b. The nature of the ascension. The ascension may be described as the visible ascent of the person of the Mediator from earth to heaven, according to His human nature. It was a local transition, a going from place to place. This implies, of course, that heaven is a place as well as earth. But the ascension of Jesus was not merely a transition from one place to another; it also included a further change in the human nature of Christ. That nature now passed into the fulness of heavenly glory and was perfectly adapted to the life of heaven. Some Christian scholars of recent date consider heaven to be a condition rather than a place, and therefore do not conceive of the ascension locally.[Cf. Milligan, The Ascension and Heavenly Priesthood of our Lord, pp. 24 ff; Swete, The Ascended Christ, pp. 8 f.; Gore, The Reconstruction of Belief, pp. 272 f.] They will admit that there was a momentary lifting up of Christ in the sight of the Eleven, but regard this only as a symbol of the lifting up of our humanity to a spiritual order far above our present life. The local conception, however, is favored by the following considerations: (1) Heaven is represented in Scripture as the dwelling place of created beings (angels, saints, the human nature of Christ). These are all in some way related to space; only God is above all spatial relations. Of course, the laws that apply in heavenly space may differ from those that apply in earthly space. (2) Heaven and earth are repeatedly placed in juxtaposition in Scripture. From this it would seem to follow that, if the one is a place, the other must be a place also. It would be absurd to put a place and a condition in juxtaposition in that way. (3) The Bible teaches us to think of heaven as a place. Several passages direct our thought upward to heaven and downward to hell, Deut. 30:12; Jos. 2:11; Ps. 139:8; Rom. 10:6,7. This would have no meaning if the two were not to be regarded as local in some sense of the word. (4) The Saviour’s entrance into heaven is pictured as an ascent. The disciples see Jesus ascending until a cloud intercepts Him and hides Him from their sight. The same local coloring is present to the mind of the writer of Hebrews in 4:14.2
